Comment 1 Evgeniy Manachkin 2008-07-23 17:09:48 UTC 
 Doing Ctrl-Alt-F1 and Ctrl-Alt-F7 a few times returns the screen to 
a functional state.
Comment 2 Evgeniy Manachkin 2008-07-23 17:14:24 UTC 
CRT+ALT+BACKSPACE resume BUG. $(

At run xrandr display one second flash.
Comment 3 Evgeniy Manachkin 2008-07-24 07:06:06 UTC 
After start xorg with the new driver the image flashes. Through "dust" on the screen parts of windows are visible. The effect is very similar to absence of vertical synchronization at CRT the monitor. Parts of the image randomly move on the screen.

Switching in the console solves a problem before restart xorg.
Comment 4 Gordon Jin 2008-07-24 20:35:48 UTC 
Does this ever work fine in the previous version? If so, which version?
Do you use external monitor?

XAA has been obsolete. Please use the default setting EXA. 
Please remove those options under driver section in xorg.conf: XAA, pageflip, triplebuffer... and retest.

Please attach the new xorg.conf and Xorg.0.log.

Next time when you report bug, better follow http://www.intellinuxgraphics.org/how_to_report_bug.html. Thanks.
Comment 5 Evgeniy Manachkin 2008-07-24 20:41:36 UTC 
>Does this ever work fine in the previous version? 

Version 2.3.2 work fine.

>Do you use external monitor?

No. Only LVDS

>XAA has been obsolete. Please use the default setting EXA. 

EXA works very slowly. Switching in EXA also does not eliminate a mistake 16823.


>Please remove those options under driver section in xorg.conf: XAA, pageflip, triplebuffer... and retest.
>Please attach the new xorg.conf and Xorg.0.log.

Ok. But hardly later.
Comment 6 Gordon Jin 2008-07-24 23:15:32 UTC 
Though the new log is not ready yet, I'd call for Zhenyu and Jesse to take a look at this, as this seems to be a regression, also there're many underrun error.
Comment 7 Jesse Barnes 2008-07-25 09:42:47 UTC 
Yeah, there are some interesting bits in the posted log:
(II) intel(0): Output configuration:
(II) intel(0):   Pipe A is off
(II) intel(0):   Display plane A is now enabled and connected to pipe A.
(WW) intel(0):   Hardware claims pipe A is on while software believes it is off
(WW) intel(0):   Hardware claims plane A is on while software believes it is
off
(II) intel(0):   Pipe B is on
(II) intel(0):   Display plane B is now enabled and connected to pipe B.
(II) intel(0):   Output VGA is connected to pipe none
(II) intel(0):   Output LVDS is connected to pipe B

Having both planes actually enabled when software thinks only one is enabled might cause problems with our DSPARB programming.

Evgeniy, can you attach your full Xorg log and xorg.conf files?
Comment 8 Evgeniy Manachkin 2008-07-25 13:39:44 UTC 
I`m update my system from mandriva repositories and rebuild driver. Now 2.4.0 version works correctly.

[root@sfbook logs_and_conf]# rpm -qa | grep x11-server-xorg
x11-server-xorg-1.4.0.90-13.3mdv2008.1


Unfortunately has not paid attention what version xorg it has been established before.

P.S. Before updating a problem it was possible режить having added in xorg.conf line Option "ForceEnablePipeB" "true". In the new version works without this line.
Comment 9 Evgeniy Manachkin 2008-07-25 13:40:53 UTC 
P.S. EXA on former in times more slowly XAA %(
Comment 10 Jesse Barnes 2008-07-25 14:01:36 UTC 
Yeah, we're working on the EXA stuff still.  Thanks for testing & reporting.
Comment 11 Chris Salch 2008-08-13 20:01:24 UTC 
Well, I've just run into this bug using the git sources on gentoo.  It appears that this commit is the culprit:  



commit 9ec36e0c8bd8a4bd7c40569412fc1a21219b5af9
Author: Olivier Fourdan <ofourdan@redhat.com>
Date:   Mon Aug 11 12:07:32 2008 -0400

    Fix DPMS off in the presence of the pipe A quirk.

    Still turn off the VGA plane, and also handle the DRI path at the end.



Everything works fine with commit 445c2e9ef8fc1d49bbb03e07bf36e0339be16a80.
Comment 12 Chris Salch 2008-08-13 20:09:21 UTC 
Created attachment 18272 [details]
Crash Log

This log states something about an error state found in the hardware, that message does not appear if the system has just been rebooted and this is the first time that X has started.
Comment 13 Gordon Jin 2008-08-13 20:15:24 UTC 
Chris, thanks for reporting and bisecting.

But please file a new bug instead reopen an old bug, since it's a new regression.
